A Pelecanimimus polyodon flees from an ambushing Concavenator corcovatus in the Cretaceous plains of Las Hoyas, Spain.

Pelecanimimus is almost a unique ornithomimid due to several of its features: the crest, the row of diminute teeth and the most recent theory/speculation, some ontological adaptations only present in dinosaurs able to fly -including aves- (quoting M. Mortimer : "large paired sterna with ossified ribs and possibly uncinates"). The animals morphology and size tell us that it being able to show powered flight is a bit unlikely, though. What this apparent adaptations means (flying ancestry in ornithomimosaurs that eventually became completely cursorial?), is up to anyones imagination. Maybe not even that since more recent discoveries suggest a bit different wing structure in primitive birds and/or birdlike dinosaurs like Archaeopteryx and Anchiornis -> [link] .

Pelecanimimus is really stealing this scene ! Wonderful details on the head, accurate soft tissues and great energy.Concavenator seems a bit baffled in comparison but I like it's jumping position (reminds me of Charles Knight). Really good job, one of your best !
